Patent JP-H09200162-A (JP)
Title: Audio signal controller
Inventor: SUZUKI HIROYUKI
IPC: H04B14/04
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent production of unexpected howling by interrupting transmission of a voice signal through a signal line when it is discriminated that signal supply' source information and signal supply destination information are the same so as to save man-hours of the operation. SOLUTION: When a talker A utters a voice to a microphone 34, the microphone 34 transduces the voice signal into an electric signal. The transduced electric signal is fed to an A/D converter 35. The A/D converter 35 converts the received analog signal into a digital signal. The digital signal obtained by conversion is fed to a channel input terminal 2 of the voice signal controller 1. When a discrimination means of the voice signal controller 1 discriminates it that signal supply source information and signal supply destination information are the same, the transmission of a signal line through the voice signal is controlled to be interrupted. Thus, the received voice signal in this case is not outputted from a voice monitor output terminal 29 of the voice signal controller 1 and then no monitor voice of the talker A is not heard from a monitor speaker 37.

Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To decrease the variation of output voltage during actual usage due to change in temperature by providing a space between a Hall element chip connected with a lead frame and a resin. SOLUTION: A Hall element chip 2 is connected electrically with a lead frame 1 so that a current flowing in the Hall element chip 2 or a voltage generating therein may be measured. A space 3 is formed around the Hall element chip 2 and the whole is molded with a packaging resin 4 as to seal the space 3, thereby obtaining a mechanical strength. In addition, the space 3 is filled with an inert gas such as argon, nitrogen, etc. Thus, the Hall element chip 2 is surrounded with a vapor phase of inert gas, and the vapor phase is packaged by the resin 4, so that no strain is applied to the Hall element chip 2 and the variation of output voltage due to change in temperature can be decreased.

Title: Electrode roll
Inventor: HIRAYAMA KEIZOU
IPC: B23K11/30
Filed: 1980-01-28
Abstract: PURPOSE: To make possible the long-time continuous use of an electrode roll by causing pressure-contacting of hard metal and hard metal at a stationary central part and a rotating part, and providing lubricating oil holding parts adjacently to the contact parts thereof.  
     CONSTITUTION: In the electrode roll, a hard-metal-made inner ring 42 is provided to a stationary central part 10 and a hard-metal-made outer ring 43 to a rotating part 20. The effluence of the conductive liquid metal contained in the gap part 32 and the entry of air into the gap part 32 from the outside are prevented by the contact part 54 of both. In this case, the lubricating oil in the micro-gap 51 between both rings 42 and 43 is sucked into the contact part 54 by capillarity, whereby an oil film is formed. This oil film exists irrespective of whether the rotation part 20 is held stopped or is rotating. Further the lubricating oil is filled in the gap 51; therefore, the sealing is perfect. An elastic part 45 makes the sliding of the contact part 54 easy, thereby preventing the abrasion of the contact surface owing to sliding.
